T cell signaling

T cell signaling is a key process in the immune system, where T cells, a type of white blood cell, recognize and respond to pathogens. When T cells encounter an antigen, they bind to it through receptors on their surface. This binding activates the T cell, leading to internal signals that promote cell growth, division, and the production of substances to attack invaders. Ultimately, T cell signaling helps coordinate the body's immune response, ensuring that it can effectively combat infections and diseases. Proper signaling is crucial for maintaining a healthy immune system and preventing unwanted immune reactions.
